BACKGROUND OF THE INVENTION Field of the Invention

The present invention relates to the field of social bookmarking and more particularly to scoring tags in a social bookmarking system.

Description of the Related Art

Content browsing refers to the retrieval and presentation of electronic content in a browser client. Content generally can include electronic documents, messages, audio, audiovisual and video materials and imagery. Most commonly, content can be stored in a server environment and published for access by content consumers over a computer communications network such as the global Internet. Content consumers, in turn, can retrieve content over the network by reference to a network address for the content. Once retrieved, the content can be presented in a browser client including not only conventional visual browsers such as the venerable Web browser, but also in alternative browsers such as those deployed in pervasive devices and those supporting different modes of presentation such as the audible presentation of material. In other cases the content can be a physical object, like a book, and content browsing can retrieve the physical location of the book, for example in a library or other information associated with the object.

Given the vast amount of content published for accessibility over the Internet, modern content browsers provide a mechanism for ably retrieving previously accessed content. Known as a “bookmark” or “favorite” (collectively referred to as a bookmark), end users can record content of interest as a bookmark. Subsequently, end users can access a list of bookmarks in order to recall the content of interest without being compelled to recall from memory the precise uniform resource indicator (URI) for the content of interest.

While bookmarking reflects the personal experience of individual users, social bookmarking provides a foundation for users within a social group to store, organize, share and search the bookmarks collectively established by the users within the social group. In operation, a social bookmarking system, users save links to memorable content. Unlike traditional bookmarks however, in a social bookmarking system the links subsequently can be published for public inspection and use, so as to provide a communal repository of bookmarks. Consequently, groups of the users can access the links encapsulated within respective social bookmarks, though the groups of users in fact may never have viewed the associated content—a prerequisite for a traditional bookmark.

Social bookmarking services often encourage users in a social network to annotate bookmarks with meta-information rather than merely storing bookmarks in a traditional file hierarchy. One such type of meta-information is a simple descriptive text label referred to in the art as a “tag”. As such, users processing annotations for a social bookmark can view the social bookmark for content along with meta-information pertaining to the bookmark, for instance the number of users having bookmarked the content. Further, some social bookmarking services infer clusters of bookmarks from the relationship of corresponding annotations. Finally, many social bookmarking services provide subscription based feeds for lists of bookmarks, including lists organized by annotations. Consequently, subscribers can become aware of new bookmarks as the bookmarks are saved, shared, and annotated by other users.

The visual display of social bookmarks can be reflected in the display of the tags used within the social bookmarking site The visual display of the tags can vary according to the number of users in a social network who have bookmarked the corresponding content with that same tag. In particular, tag clouds often include tags with a font size commensurate with a number of users in the social network whom have bookmarked the corresponding content with that same tag. In this way, a visual glance of the content will indicate which aspects of the content are most interesting to the social network at large as the font size of the different words in the content will vary relative to the other words according to the popularity of the different words.

The visual display of tags can also vary according to the overall number of uses of a particular tag across the entire social bookmarking site. In this regard, tag clouds can be used to indicate which topics are most prominent in the entire site.

As tagging of Web content becomes more popular and pervasive, it can be problematic in determining how to represent the knowledge of multiple tagging systems so that the wisdom of crowds is represented by an aggregate scoring of the wisdom of multiple crowds across different social bookmarking system. These multiple crowds may represent multiple crowds in a single company, or indeed individuals on other servers in different companies or shared spaces. In situations where end users desire an ability to use multiple bookmarking systems, there is no means today to aggregate this content with a view towards combined normalized scoring of tags.

BRIEF SUMMARY OF THE INVENTION

Embodiments of the present invention address deficiencies of the art in respect to social bookmarking and provide a novel and non-obvious method, system and computer program product for aggregating scoring of tagged content across social bookmarking systems. In an embodiment of the invention, a method for aggregating scoring of tagged content across social bookmarking systems can be provided. The method can include combining tag scores for a tag in content across multiple different social bookmarking systems into a single aggregate tag score and applying the single aggregate tag score to the tag in the content. In this regard, combining tag scores for a tag in content across multiple different social bookmarking systems into a single aggregate tag score can include computing either a simple or a weighted average of the tag scores for the tag to produce the single aggregate score.

In another embodiment of the invention, a social bookmarking data processing system can be provided. The system can include multiple different social bookmarking systems coupled to multiple different browser clients over a computer communications network. The system further can include score aggregation logic executing in a host server coupled to the social bookmarking systems and the browser clients. The logic can include program code enabled to combine tag scores for a tag in content across multiple different social bookmarking systems into a single aggregate tag score, and to apply the single aggregate tag score to the tag in the content. In this regard, the single aggregate tag score can be a simple average of the tags scores for the tag from the different social bookmarking systems, or the single aggregate tag score can be a weighted average of the tags scores for the tag from the different social bookmarking systems.

Additional aspects of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. The aspects of the invention will be realized and attained by means of the elements and combinations particularly pointed out in the appended claims. It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory only and are not restrictive of the invention, as claimed.

The embodiments illustrated herein are presently preferred, it being understood, however, that the invention is not limited to the precise arrangements and instrumentalities shown, wherein:

FIG. 1 is a schematic illustration of a social bookmarking data processing system configured for aggregating scoring of tagged content; and,

FIG. 2 is a flow chart illustrating a process for aggregating scoring of tagged content across social bookmarking systems.

DETAILED DESCRIPTION OF THE INVENTION

Embodiments of the present invention provide a method, system and computer program product for aggregating scoring of tagged content across social bookmarking systems. In accordance with an embodiment of the present invention, the scores for a tag in content from multiple different social bookmarking systems can be combined into an aggregated score and reflected in the content, for example as a tag cloud. For example, the aggregated score can be an average score amongst the different social bookmarking systems for the tag, or the aggregated score can be weighted according to a number of samples received in each of the different social bookmarking system. Optionally, different social bookmarking systems can be included in the aggregation according to administrator preference, user preference or both.

In further illustration, FIG. 1 schematically depicts a social bookmarking data processing system configured for aggregating scoring of tagged content The system can include multiple different social bookmarking servers 130 with corresponding social bookmarking systems 150 configured for coupling to multiple different content clients 110 with respective content browsers 140 over computer communications network 120. Each social bookmarking system 150 can measure a frequency of tagging content as a social bookmark within a corresponding social network. The measured frequency can include a number of tags applied to all content and a number of tags applied for particular content. The measured frequency further can be stored within a data store of tag scores 160.

Notably, a host server 170 can be coupled to each of the social bookmarking servers 130 and the clients 110 over the computer communications network. The host server 170 can include score aggregation logic 190 coupled to a data store of aggregated scores 180. The logic 190 can include program code enabled to aggregate different scores for the same tag from each of the different social bookmarking systems 150 into a single aggregated score for the tag. The program code of the score aggregation logic 190 further can be enabled to provide the aggregated score to the different clients for visual presentation within the respective content browsers 140, for instance as a tag cloud.

In further illustration of the operation of the score aggregation logic 190, FIG. 2 is a flow chart illustrating a process for aggregating scoring of tagged content across social bookmarking systems. Beginning in block 210 content for a page can be loaded and in block 220 a tag within the content can be selected for processing. In block 230 a first contributing social bookmarking system can be selected and in block 240 the score and frequency data for the tag can be retrieved. In this regard, the score can include a number of users of the social bookmarking system having applied the tag and a number of tags applied by all users of the social bookmarking system.

In decision block 250 if additional social bookmarking systems remain to be processed, the process can repeat through block 230 for a next social bookmarking system. Optionally, the number and nature of the social bookmarking systems considered for aggregation can be limited by an administrator or by the end users. For instance, users in one geographic region can enjoy one set of social bookmarking systems which may differ from users in other geographic regions. Access control further can be applied to the end users in determining which end users can aggregate tag scores from which social bookmarking systems.

In decision block 250, when no further social bookmarking systems remain to be considered, in block 260 the tag scores collected from the different social bookmarking systems can be combined into an aggregate score for the tag. In this regard, the aggregate score can be a simple average of the tag scores from each social bookmarking system, or the aggregate score can be a weighted average based upon the volume of tags applied in each social bookmarking system. In any event, in block 270 the aggregate score can be applied to the tag in the content and visually presented accordingly, for example in a tag cloud. In decision block 280, if additional tags remain to be processed in the content, the process can continue in block 220 with the selection of a different tag. Otherwise, the process can end in block 290.

Notably the process described herein can occur upon detecting a change in the tag scores in the different social bookmarking systems, or the process can be performed in batch during off hours at a scheduled interval. Embodiments of the invention can take the form of an entirely hardware embodiment, an entirely software embodiment or an embodiment containing both hardware and software elements. In a preferred embodiment, the invention is implemented in software, which includes but is not limited to firmware, resident software, microcode, and the like. Furthermore, the invention can take the form of a computer program product accessible from a computer-usable or computer-readable medium providing program code for use by or in connection with a computer or any instruction execution system.

For the purposes of this description, a computer-usable or computer readable medium can be any apparatus that can contain, store, communicate, propagate, or transport the program for use by or in connection with the instruction execution system, apparatus, or device. The medium can be an electronic, magnetic, optical, electromagnetic, infrared, or semiconductor system (or apparatus or device) or a propagation medium. Examples of a computer-readable medium include a semiconductor or solid state memory, magnetic tape, a removable computer diskette, a random access memory (RAM), a read-only memory (ROM), a rigid magnetic disk and an optical disk. Current examples of optical disks include compact disk—read only memory (CD-ROM), compact disk—read/write (CD-R/W) and DVD.

A data processing system suitable for storing and/or executing program code will include at least one processor coupled directly or indirectly to memory elements through a system bus. The memory elements can include local memory employed during actual execution of the program code, bulk storage, and cache memories which provide temporary storage of at least some program code in order to reduce the number of times code must be retrieved from bulk storage during execution. Input/output or I/O devices (including but not limited to keyboards, displays, pointing devices, etc.) can be coupled to the system either directly or through intervening I/O controllers. Network adapters may also be coupled to the system to enable the data processing system to become coupled to other data processing systems or remote printers or storage devices through intervening private or public networks. Modems, cable modem and Ethernet cards are just a few of the currently available types of network adapters.
